LIQUID-AGITATING MECHANISM.

Application filed July 1, 1920. Serial No. 393,429.

To all whom it may concern: 7

Be it known that I, FRANK M. SLoUGH, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Liquid- Agitating Mechanisms, of which the following is a full, clear, concise, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to liquid agitating mechanisms, and particularly to such mechanisms wherein liquid contained in a tank is moved in diverse directions therein, under the influence of one or more propellers suitably rotated by a source of power.

It is an object of my invention to produce such adevice as may be simply and cheaply constructed and will operate most eificiently, and in which mechanism the sanitary conditions, when the device is used for processing food. products, are maintained to a high standard.

It has heretofore been proposed to place more than a single rotatable propeller in a mixing tank substantially of the form herein contemplated, but such efforts have, so far as I am aware, beenmore or less unsuccessful, because either the second propeller neutralizes to a large degree the effect of the first propeller, or merely passes along currents set in motion by the other propeller and only slightly adds to the velocity of such currents.

In my present invention, 1 am enabled to use a plurality of propellers, herein illustrated as two propellers, which co-act in a new and novel way to produce a maximum of liquid agitation, and each propeller at the same time causing currentswhich deflect the currents produced by the other propeller without detracting from their velocity or ability to perform the function of mixing.

Other objects of my invention and the invention itself will. be better understood by referring to the drawings accompanying this specification.

Figure 1 of the drawings shows an embodiment of myinvention in vertical cross section.-

Figure 2 shows a plan view of said embodiment, the view of Figure 1 being taken on a line I-I of Figure 2.

Referring now to the drawings, at A-A are shown the curved sidewalls of a tank,

herein illustrated as cylindrical, and at B is shown a downwardly inclined bottom wall thereof, the side walls and bottom wall bee dium, and an opening G is provided for the,

egress thereof.

Passing through a side wall'o'f the tank, at points H and J, are a plurality of"propeller shafts, herein illustrated as being two in number, said shafts being shown at K and L. d

On the ends of the said shafts, inside the tank, are mounted a pair of propellers N and O and on the opposite ends thereof, outside the tank, are shown pulleys P and P, whereby power from a motor may be caused to rotate the said propeller shafts carrying the said propellers.

The propeller shafts are herein illustrated as being mounted substantially in the same horizontal plane and substantially parallel to each other and to the axis of the tank, each preferably being equidistant from the plane of the saidax'is; but it is obvious that these precise relations may be departed from somewhat, and still realize the mode of operation, and the results secured thereby, by the use of this invention.

The propellers are preferably pitched and rotated in such a direction as will produce the same thrust tendency upon liquid in its vicinity, that is, they may be both left handed propellers, both operating counterclockwise, or one of them may be a lefthanded propeller and the other a righthanded propeller, but rotating in opposite directions; I contemplate both arrangements and directions of rotation.

By this arrangement portions of the liquid contents of the tank may pass from the propellers in parallel paths, reacting, however, on each other so as to cause deflection from the said paths; portions of the said currents striking the side walls of the said tank and are caused to be deflected thereby, setting up i the fact that currents are caused to be propelled around and around the central vertical axis of the tank producing What is known in the art as a merry-go-round effeet, which is not conducive to the thorough inter-mingling of the various particles of the liquid contents of the tank, nor to their uniform exposure to the thermal effects of the side and bottom Walls of the tank as herein contemplated.

Having thus described my invention, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described, but Without departing from the spirit and scope of my invention. My invention is defined in the following claims:

1. In combination, a tank, a propeller, a propeller shaft, said propeller being adapted to be rotated by the said shaft, cylindrical side Walls for the said tank, said propeller being adapted to be rotated in a vertical plane located parallel to but on one side of a tank diameter, the axis of rotation being in a vertical plane not corresponding to a tank diameter, but parallel thereto, the bottom of the tank being inclined to the plane to the attaching edge of the side Walls.
